Problems solved by technology

[0004] However, in traditional lighting fixtures, after the light from the light-emitting component enters the light-guiding component through the light-incident surface of the light-guiding component, the light exits from the light-emitting surface of the light-guiding component, which can only provide a monotonous lighting effect
In other words, traditional lighting fixtures cannot present a variety of lighting effects, which is not conducive to the development of lighting fixtures

[0035] Figure 1A It is a schematic top view of the lighting device according to the first embodiment of the present invention. Figure 1B for along Figure 1A The cross-sectional schematic diagram of the section line A-A'. Figure 1C for Figure 1B The three-dimensional side view of the part circled E in the direction perpendicular to the paper surface shows an example of the arrangement of the first light emitting unit 132 of the light bar 130a.

[0036] Please refer to Figure 1A as well as Figure 1B , the lighting device 100a includes: a first light guide 110 , at least one second light guide 120 and a light bar 130a. The first light guide 110 has a first surrounding light incident surface 112 , a first light emitting surface 114 and a first light reflecting surface 116 . The first light emitting surface 114 and the first light reflecting surface 116 are adjacent to the first surrounding light incident surface 112 . The second light guide body 120 is disposed above the...

[0053] Figure 2A It is a schematic top view of the lighting device according to the second embodiment of the present invention. Figure 2B for along Figure 2A The cross-sectional schematic diagram of the section line B-B'. It should be noted that, Figure 2A Only the first light guide body 110 and the second light guide body 120 are shown to clearly show the relative positions of the first light guide body 110 and the second light guide body 120 .

[0054] Please also refer to Figure 2A as well as Figure 2B , the lighting device 100b and Figure 1A and Figure 1B The illustrated lighting device 100a is substantially similar, except that in the lighting device 100b, the second light guide body 120 is disposed above the periphery of the first light guide body 110, and the edge of the second light guide body 120 is a distance from the second light guide body 110. edge of a light guide body 110, and move a certain distance D into the first light guide body 110, which is ...

[0058] image 3 A schematic top view of the lighting device according to the third embodiment of the present invention is shown. Please refer to image 3 The lighting device 100c is similar to the lighting device 100a in FIG. 1 , and only a top view of the lighting device 100c is shown here.

[0059] The difference between the lighting device 100c and the lighting device 100a is that the first light guide body 110 of the lighting device 100c is a polygonal light guide plate ( image 3 shown as a rectangle), and the second light guide body 120 is a plurality of elongated light guide covers 120A˜120D, which are correspondingly arranged on each side of the polygonal light guide plate (the first light guide body 110 ). It can be noticed that the edge of the second light guide body 120 is adjacent to the edge of the first light guide body 110 .

[0060] image 3 What is shown is a rectangular first light guide body 110; however, the first light guide body 110 can be any polygon...

Abstract

The invention relates to an illuminating device, which comprises a first light guider, at least one second light guider and a light bar. The first light guider is provided with a first peripheral light incident surface, a first light emergent surface and a first light reflecting surface, the first light emergent surface is opposite to the first light reflecting surface, and the first light emergent surface and the first light reflecting surface are adjacently connected to the first peripheral light incident surface; the second light guiders are disposed above the periphery of the first light guider, and each second light guider is provided with a second peripheral light incident surface; the light bar provides a plurality of light beams; and a first part of the light beams enters the first light guider from the first peripheral light incident surface, and a second part of the light beams enters the second light guiders via the second peripheral light incident surfaces. The illuminating device has the advantage that a peripheral illuminating effect can be realized so as to realize a visual performance with halation. In addition, the intensity of the halation can be adjusted by the aid of light intensity proportion of emitted light of the first light guider to emitted light of the second light guiders.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a light guide in the illuminating device. Background technique [0002] A light source module using a light-emitting component and a light-guiding component has been widely used in the lighting field. Generally speaking, the light provided by the light-emitting component enters the light-guiding component and propagates, and then the light is emitted from the light-emitting surface of the light-guiding component to form the required illumination source. [0003] In recent years, with the advancement of lighting technology, the above-mentioned light source modules have been gradually applied in many lighting fixtures. Among various light emitting components, Light Emitting Diode (LED) has become the mainstream due to its high brightness, low power consumption and low pollution. [0004] However, in traditional lighting fixtures, after the light from the light-emitting component enters t...
